Complications of Gastritis
The complications of gastritis can range from minor uncomfortable cases to serious health risks, especially if the condition is left untreated. Gastritis can erode the stomach lining, which will allow acid to cause deeper damage and making the stomach more vulnerable to infection, bleeding, and cancerous changes.
Peptic Ulcers
Untreated gastritis may lead to ulcers in the stomach or duodenum
Symptoms include burning pain, nausea, vomiting, and sometimes bleeding
May cause perforation in severe cases, leading to a life-threatening emergency
Internal Bleeding
Inflamed or eroded stomach lining can cause bleeding
Signs include:
Vomiting blood (haematemesis)
Black, tarry stools (melena)
Fatigue or shortness of breath, particularly in cases of slow, chronic bleeding
Blood transfusions and endoscopic intervention may be required in severe cases.
Anaemia
Ongoing blood loss can lead to iron-deficiency anaemia
Autoimmune gastritis may cause pernicious anaemia by reducing absorption of vitamin B12
Symptoms include weakness, pale skin, tingling in hands and feet, and cognitive changes
Stomach Cancer
Chronic gastritis, particularly caused by H. pylori or autoimmune activity, increases the risk of:
Gastric adenocarcinoma
MALT lymphoma (a type of cancer affecting stomach lymphoid tissue)
Regular monitoring and eradication of H. pylori reduce the long-term cancer risk
Delayed Gastric Emptying (Gastroparesis)
Chronic inflammation may interfere with stomach motility
Can cause bloating, fullness, and nausea, especially after meals
Most common in people with diabetes-related gastritis
Quality of Life Impact
Recurrent symptoms may affect appetite, sleep, and emotional wellbeing
Many people with chronic gastritis also experience anxiety about eating or develop food avoidance patterns
Psychological support and nutritional guidance are often beneficial
Complications of Gastritis
Preventing the complications of gastritis involves early diagnosis, effective treatment, and lifestyle adjustments to reduce stomach irritation and support healing.
